Gibbs free energies of H+, water and OH− adsorbed on the atop sites of the step edge of Pt(110), relative to the bare surface in (a) acid conditions, pH = 0 and (b) basic conditions, pH = 9. Free energies are estimated from calculations at 0 V vs SHE and include vibrational and entropic contributions (see Methods section for details).
